Thanks, fixed.

Yes, the C standard says:
"If the first enumerator has no =, the value of its enumeration constant is 0. Each subsequent enumerator with no = defines its enumeration constant as the value of the constant expression obtained by adding 1 to the value of the previous enumeration constant."

See this draft of C99 for example, in 6.7.2.2 Enumeration specifiers:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf

(Turns out non-drafts are not published for free.)
